I want a formula to display at Epic level all a rolled up view of all the "component/s" identified in child issues (e.g., Features/Stories) or linked issues (via a specific type of linking - "delivers".
So that at Feature level - I can see a rolled up view of all component/s from linked Stories - and at Epic level - I can see a rolled up view of all the components from child Stories and Features).
N.B. - Our Jira issue hierarchy is as follows (e.g., Child > Parent) = Story > Feature > Epic
